A project is underway to investigate sustainable and alternative cultivation techniques using biological material, with a focus on the by-products of grape, blueberry, strawberry, and asparagus cultivation. These by-products will be transformed into biomolecules through a process of bio-extraction and synthetic upgrading, with the potential to be used as raw materials for fine chemicals, medicines, or high-quality materials. The project is a collaboration with growers and sector organizations in Flemish and Dutch Limburg, and will also explore how cultivation and breeding conditions of food crops impact the potential of the residual flow.
